I'm sure everyone will be recommending the Adaptec 1542 controller.
Its reasonable fast and well supported by most everyone. The
WD FASST scsi board would make a second choice as it will be
supported by everyone using System V Release IV - its part
of the AT&T base port for the 386.

Another option people may laugh at but one which I like is the
Seagate ST-01 controller. I've made heavy modifications to the
Public Domain driver for UNIX and am acheiving speeds twice
that of the Adaptec controller on the same drive.
(Though I'm testing it against the ESIX scsi implementation
 which if like their other drivers has probably has problems.
